ABSTRACT

A lavatory faucet is fixed on a basin and contains: a body and a fixing device. The body includes a housing and a supply pipe assembly; the fixing device includes a mounting seat, two screw rods, and two clamping blocks; the basin includes a central orifice, a left orifice, and a right orifice. The mounting seat includes an upper fitting sleeve, two extending wings for abutting against a top face of the basin, and two support feet. The upper fitting sleeve has a channel defined therein relative to the central orifice, each extending wing has a through hole to insert each support foot, and each support foot has a first stopping fence. Each screw rod extends out of the through hole and is rotated above the mounting seat, each clamping block is screwed with each screw rod and is limited by the first stopping fence as rotating each screw rod.

FIELD OF THE INVENTION

The present invention relates to a lavatory faucet fixed on a basin with a central orifice, a left orifice, and a right orifice.

BACKGROUND OF THE INVENTION

A conventional facet is installed in a narrow space below a basin which is located in a kitchen or a bathroom.

A positioning structure for a faucet disclosed in U.S. Pat. No. 8,763,175 B2 is fixed on the basin from an upper end of the basin. The faucet contains a body and a fixing device for installing the faucet on the basin from the upper end of the basin. The fixing device includes a mounting seat, two screw rods, and two clamping blocks. The mounting seat is inserted into an orifice on the basin and is employed to fix the body and to insert a supply pipe assembly. The supply pipe assembly has a first inlet pipe for flowing cold water, a second inlet pipe for flowing hot water and an inflow pipe for flowing a mixed water of the cold water and the cold water. The two screw rods are rotated to insert through the mounting seat from the orifice and are fixed by the two clamping blocks. When the two screw rods are rotated above the basin, they are positioned by the two clamping blocks and two stop stems on the mounting seat, such that the two clamping blocks are driven to force a bottom face of the basin, and the fixing seat and the body are clamped on the basin.

However, the faucet is applicable for the basin with a single orifice, because a diameter of the orifice is larger than 34 mm. Therefore, when the basin has three orifices, a diameter of which is less than 32 mm, the mounting seat cannot be fixed in the three orifices. Even through a size of the mounting seat is reduced, a channel in the mounting seat is decreased accordingly, so the supply pipe assembly cannot be mounted in the channel.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

One aspect of the present invention is to provide a lavatory faucet which is capable of overcoming the shortcomings of the conventional lavatory faucet.

To obtain the above, a lavatory faucet is fixed on a basin and contains: a body and a fixing device. The body includes a housing and a supply pipe assembly connecting with the body to delivery water; the fixing device includes a mounting seat, two screw rods, and two clamping blocks. The basin includes a central orifice, a left orifice, and a right orifice.

The mounting seat includes an upper fitting sleeve for connecting with the housing, two extending wings extending outwardly from a bottom end of an outer wall of the upper fitting sleeve to abut against a top face of the basin, and two support feet extending downwardly from two bottom ends of two outer walls of the two extending wings to insert through and to retain with the left orifice and the right orifice of the basin; the upper fitting sleeve has a channel defined therein relative to the central orifice of the basin so that the supply pipe assembly extends out of the central orifice via the channel; each extending wing has a through hole to insert each support foot; and each support foot has a first stopping fence formed on an outer wall thereof.

Each screw rod extends out of the through hole of the mounting seat and is rotated above the mounting seat.

Each clamping block is screwed with each screw rod and is limited by the first stopping fence of each support foot as rotating each screw rod, such that each clamping block moves upwardly to retain with a bottom face of the basin and to clamp the mounting seat and the body on the basin.

Thereby, the lavatory faucet of the present invention has advantages as follows:

1. The lavatory faucet is applicable for the basin with the central orifice, the left orifice, and the right orifice, the diameter of which is less than 32 mm.

2. The diameter of the channel is larger than that of the central orifice, and the two support feet are retained with the left orifice and the right orifice by ways of the two screw rods and two clamping blocks so that the mounting seat is fixed on the basin, and only the supply pipe assembly is inserted through the central orifice easily.

3. The two screw rods are rotated, and the two clamping blocks screwed with the two screw rods are rotated to accommodate in the two support feet or below two stop columns so that the fixing device is mounted on the basin easily, thereafter the two screw rods are rotated above the mounting seat of the basin so that the two clamping blocks engage with the bottom face of the basin tightly, thus fixing the fixing device. Accordingly, the body is fitted on the upper fitting sleeve of the fixing device, the supply pipe assembly is inserted through the central orifice of the basin from the channel of the upper fitting sleeve, thus fixing the lavatory faucet easily and quickly.
